The supracrustals of the Indian Archean are broadly divisible into an older and a younger sequence. Older belts are characterized by argillites and chemogenic sediments of high Mg, Fe, Al, Cr, and Ni ...

This separation led to the illusion as if the plate tectonics theory is not applicable to Precambrian geology, particularly in interpreting the fundamental geological characteristics of Archean ...

The continents primarily consist of cratons and orogenic belts, of which cratons predominantly originated 1.8 billion years ago, serving as crucial constituents of the Earth’s surface. Most of the ...

Precambrian time covers the vast bulk of the Earth's history, starting with the planet's creation about 4.5 billion years ago and ending with the emergence of complex, multicelled life-forms ...

In contrast to the studied Archean rocks, late-Precambrian sedimentary basins on Earth contain a wide variety of rocks whose organic material is relatively well preserved and can be examined for ...

My research has concentrated in several fields in petrology. My major fields of interest include: Geologic evolution of the Wyoming Province: The Wyoming province is one of the oldest Archean ...
